TRHW-9000E Fully Automatic Quantitative Isothermal Calorimeter Introduction: Suitable for measuring the heat value of solid or liquid combustibles such as coal, petroleum, biomass fuels, waste fuels, cement black raw materials, grains, feed, etc. in industries or departments such as electricity, coal, metallurgy, petrochemicals, coalification, cement, papermaking, geological exploration, agriculture and animal husbandry, pharmaceutical research, and teaching. characteristic: 1. Flexible placement method: The instrument consists of a main controller and a temperature controller, which can be placed flat on the experimental table or placed below the experimental table with the temperature controller; 2. Stable water volume: This instrument uses a stable and reliable measuring cup for quantitative measurement, ensuring the long-term stability of water volume; 3. Simple waterway: The instrument uses three pumps and three valves as a whole, which greatly simplifies the waterway compared to traditional instruments. The waterway is reliable and the components are easy to maintain; 4. Constant water temperature: Added a chiller controller that can display the temperature of the water tank in real time and adjust the temperature of the water tank; 5. Waterway filtration: Add a filter to the inner cylinder to ensure that impurities (such as ignition wires) in the inner cylinder do not damage the waterway pump valve; 6. Visible liquid level: It is convenient to grasp the progress of water addition and timely supply water to the instrument after long-term experiments; 7. Bucket lid with lock: The experiment is safe and reliable, the bucket lid is tightly sealed, and the upper end of the inner cylinder is not affected by external airflow; 8. Diverse testing modes: This instrument has both conventional and rapid testing modes to meet the needs of different customer groups; 9. Stable inner cylinder environment: water is added to the lid of the barrel, a large amount of water is added to the outer cylinder, and there is no residual water in the water discharge pipeline of the inner cylinder, ensuring the stability and reliability of the experimental environment around the inner cylinder; 10. Experimental procedure: Before ignition, determine the temperature difference range between the inner and outer cylinders. After the experiment, clean the inner cylinder and oxygen bomb to ensure the stability and consistency of the environment during the experiment. After the experiment, remove the residual heat in a timely manner without affecting the next experiment; 11. Conventional method: Based on the classical Ruifang formula, combined with the experimental process and structure of the instrument, a simplified classical experimental method - conventional method - is explored. Numerous experiments have shown that conventional methods are equivalent to classical methods. This experimental method can withstand environmental temperature fluctuations of about 5 ℃; 12. Rapid method: Based on the reversible process of heat capacity and heat generation, a rapid method is proposed, with an experimental period of 10-12 minutes. Can withstand environmental temperature fluctuations of around 4 ℃. Technical parameters: Temperature resolution: 0.0001 ℃ Test cycle: ≤ 15 minutes (conventional method), ≤ 10 minutes (rapid method) Single experiment outer cylinder water temperature constant accuracy: 0.08 ℃ Long term experimental system water temperature constant accuracy: 1 ℃ Sample weight: Determine the sample weight based on its heat generation range, with coal samples typically weighing 1g Precision: RSD ≤ 0.1% Accuracy: The test results are within the allowable range of the standard sample Calorific value range: 15000J/g~35000J/g (3500Cal/g~85000 Cal/g) Thermal capacity fluctuation: ≤ 0.2% within one year Power supply: 220V ± 30V, 50Hz/60Hz Dimensions: Main controller (L × W × H): 540mm × 530mm × 600mm Temperature controller (L × W × H): 270mm × 530mm × 500mm Weight: Main controller 40kg, temperature controller 35kg Power: Computer<300W, calorimeter host<200W
